How much work is required to lift a 600-kg satellite to an altitude of 1⋅1061⋅106 m above the surface of the earth? The gravitational force is =m/2F=GMm/r2, where M is the mass of the earth, mm is the mass of the satellite, and r is the distance between them. The radius of the earth is 6.4⋅1066.4⋅106 m, its mass is 6⋅10246⋅1024 kg, and in these units the gravitational constant, G, is 6.67⋅10−11
